To all whom it may concern.-

Be it known that I, EDWARD GREEN, a sub ject of the Queen ofGreat Britain, residing at Wakefield, in the county of York, England, have invented a new and useful im iirovement in lids or covers for i'uel-economizers and in the method of fixing them in position and in removing them therefrom, (for which I have obtained a patent in Great Britain, No. 3,794, bearing date August 9, 1882,) of which the following is a specification.

The object of my invention is an improvement on lids or covers for fuel-economizers and in the method of fixing them in position and in removing them thcreform.

l-Iitherto lids or covers have been fitted to fuel-economizers by lodging them on the top of the casing, so asto overlap the openings, and then fixing them in position by under straps and screws.

According to my invention, which I illustrate in the-annexed drawings, Figures 1 and 2, I make the lids or covers A A with tapered edges B B, to fit correspondi ugly-shaped edges, (J U, of the aperture 1) in the casing E, and be drawn up into position by a temporary fitting-bolt or otherwise. The lid or cover has preferably a channeled aperture, (1, at its upper part, and also a Lewis hole for the reception of the Lewis bolt F, which is fitted by a screw, G, to an upper cross-bar or saddle, H, gaged to fit over any of the apertures in the casing. The edges of the lids may be threaded, as at B, to screw upward into position, or they may be plain to fit the apertures D by surface contact.

The temporary upper cross-bar or saddle, II, is applicable for removing any of the covers so fitted by a reverse movement of the screw G. The ends of the saddle may be provided with Lewis bolts, to engage in Lewis holes, if required.

The lids or covers are put into the casing through the neck of the connection, and when in position are held firmly by the internal pressure, which soon set-s them.

I claim as my invention In a fueteeonomizcr, the combination, with a casing having apertures 1), formed with tapering edges, of the covers A, located below the top of said casing and provided with ta pered edges corresponding with the edges of said apertures, a temporary saddle, H, and a screw, i, working in said saddle and adapted to be detachably"connected with said covers successively, whereby the several covers are secured in the apertures D by internal pressu re, while the saddle and screw are detached for use in placing other covers in position, substantially as described.

In witness whereot'l have hereunto signed my name in the presence of two subscribing witnesses.

EDVARD GREEN.
